Do I need to purchase a TV tuner when I buy a Media Center PC?

Many Media Center PCs come equipped with a single TV tuner that captures your TV signal from a cable, satellite, or antenna source. Media Center PCs can also be equipped to handle multiple tuners. For example, if your Media Center PC comes with more than one TV tuner, you can record two shows while you watch a third recorded show.

If your Media Center PC is not equipped with a TV tuner, it is possible to upgrade.
